Measurements of vector magnetic field using multiple electromagnetically induced transparency resonances in Rb vapor

We study intensity distribution of transmission resonances under the conditions of electromagnetically induced transparency (EIT) with lin||lin configuration in 87Rb vapor. We demonstrate that for various orientations of the external magnetic field all seven resolved EIT resonances exhibit maxima or minima at certain directions of the linear polarization of the laser field. This effect can be used for development of a high-precision vector EIT magnetometer.Comment: 4 pages, 4 figure

Measurements of the magnetic field vector using multiple electromagnetically induced transparency resonances in Rb vapor

We study the dependence of electromagnetically induced transparency (EIT) resonance amplitudes on the external magnetic field direction in a linearly polarized bichromatic light (lin||lin) configuration in (87)Rb vapor. We demonstrate that all seven resolvable EIT resonances exhibit maxima or minima at certain orientations of the laser polarization relative to the wave vector and magnetic field. This effect can be used for the development of a high- precision EIT vector magnetometer

Coherent population trapping resonances with linearly polarized light for all-optical miniature atomic clocks

We present a joint theoretical and experimental characterization of the coherent population trapping (CPT) resonance excited on the D1 line of 87Rb atoms by bichromatic linearly polarized laser light. We observe high-contrast transmission resonances (up to 25%), which makes this excitation scheme promising for miniature all-optical atomic clock applications. We also demonstrate cancellation of the first-order light shift by proper choice of the frequencies and relative intensities of the two laser field components. Our theoretical predictions are in good agreement with the experimental results.Comment: 8 pages, 7 figure

Association of the dopamine receptor (DRD4, DAT) gene polymorphisms with vital exhaustion in an open population among 25—64-year-old men (Novosibirsk): Epidemiological study according to the WHO MONICA-psychosocial program

Objective: to study the association of the DRD4, DAT genes with vital exhaustion in an open 25—64-old-year male population. A random representative sample of 657 men aged 25—64 years, living in one of the Novosibirsk districts was examined within the WHO MONICA project in 1994. The MONICA-MOPSY test was used to estimate the level of vital exhaustion. The examined DRD4, DAT gene Polymorphisms were genotypes in the Laboratory of Molecular Genetic Studies, Therapy Research Institute, Siberian Branch, Russian Academy of Medical Sciences (Novosibirsk). Results. The genotype containing allele 7 in the dopamine receptor subtype 4 (DRD4) gene, as well as genotype 9/9 in the dopamine-transporter protein (DAT) gene are significantly associated with the high level of vital exhaustion. Conclusion. The vital exhaustion is significantly associated with certain DRD4, DAT gene polymorphisms in the open 25—64-year-old male population of Novosibirsk
